High Amounts of Sugar Harmful to Livers of Even Healthy Men

November 3, 2017 in LifeCare Health Services

There has been much research in the last few decades about the harms that too much sugar can have on the body. A recent study published in Clinical Science contributes more information about sugar and the body. In this case, it’s about sugar’s effects on the liver. According to their findings, they saw that consuming high amounts of sugar can harm the livers of even otherwise healthy men.

For this study, scientists compared a group of men who did have non-alcoholic fatty liver disease (NAFLD) to those who did not. NAFLD is where the liver stores excess fat. In some cases, NAFLD can lead to other liver complications and heart issues. In this trial, they tracked a group of middle-aged men who had either high or low levels of fat in the liver. The men were randomly assigned to either a high-sugar or low-sugar diet and had to switch over to the other diet at a certain interval. During this time, researchers tracked the men’s liver health.

Both groups began having high amounts of fat storage in their livers when they were on the high sugar diet. They also began having metabolic changes in fat metabolism. The types of changes that occurred are known to be markers for cardiovascular issues. The healthy men also began to show symptoms that were like NAFLD. This shows that one does not have to have a predisposition towards NAFLD to develop it. This is a concern to health professionals, because NAFLD is on the rise in children and adults.

When it comes to sugar, it’s important to keep track of how much you are consuming. Too much of any one thing can spell negative health consequences.
